# This script can install or uninstall acer turbo fan service. It means, that your turbo fan button still will be available even after rebooting.
# To install service just run this script as the root (sudo) user.
# After installation you can manage it as a usual service manually. Example: 'systemctl start/stop turbo-fan',  'systemctl enable/disable turbo-fan'
# To uninstall service, run this script with 'remove' argument. Example: 'sudo bash ./install_service.sh remove'.
# Note!!! Before removing, don't forget to switch off the turbo button because you will have forever turbo fan :)
